Periodic Trends - Chemical Bonds

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

What type of bond involves the equal sharing of electrons?

Back

A non-polar covalent bond involves the equal sharing of electrons.

Front

What type of bond involves the unequal sharing of electrons?

Back

A polar covalent bond involves the unequal sharing of electrons.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that involves the electrostatic attraction between oppositely charged ions.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the charge of a sodium ion (Na+)?

Back

The charge of a sodium ion is +1.

Front

What is the charge of a chloride ion (Cl-)?

Back

The charge of a chloride ion is -1.

Front

What is a non-polar bond?

Back

A non-polar bond is a type of covalent bond where the electronegativity difference between the two atoms is negligible.

Front

What is a polar bond?

Back

A polar bond is a covalent bond between two atoms with different electronegativities, resulting in a partial positive and negative charge.
